## Τι είναι το Æternity;

Το Æternity είναι μια πλατφόρμα blockchain που προέκυψε με το όραμα να αντιμετωπίσει μερικά από τα πιο επείγοντα ζητήματα που αντιμετωπίζουν η τεχνολογία blockchain και τα κρυπτονομίσματα: η κλιμακωσιμότητα, η ασφάλεια και η αποτελεσματική ένταξη με δεδομένα του πραγματικού κόσμου. Ιδρύθηκε το 2016 και λανσάρισε το κύριο δίκτυό του το 2018, το Æternity παρουσιάζει μια καινοτόμο προσέγγιση για την επίτευξη υψηλής κλιμακωσιμότητας και τη διευκόλυνση της απρόσκοπτης ένταξης δεδομένων του πραγματικού κόσμου μέσω της πλατφόρμας του.

Στην καρδιά της καινοτομίας του Æternity βρίσκεται η μοναδική αρχιτεκτονική του blockchain, η οποία περιλαμβάνει αμιγώς λειτουργικά έξυπνα συμβόλαια και αποκεντρωμένους οράκουλους. Αυτοί οι οράκουλοι είναι κρίσιμοι για την ενσωμάτωση εξωτερικών δεδομένων στο blockchain με έναν αξιόπιστο τρόπο, επιτρέποντας στα έξυπνα συμβόλαια να εκτελούνται με βάση πληροφορίες του πραγματικού κόσμου χωρίς να βασίζονται σε τρίτους διαμεσολαβητές. Αυτή η δυνατότητα είναι ιδιαίτερα ωφέλιμη για μια ευρεία γκάμα εφαρμογών, από τις χρηματοοικονομικές υπηρεσίες έως τη διαχείριση εφοδιαστικής αλυσίδας, όπου τα ακριβή και εγκαίρως δεδομένα είναι καθοριστικής σημασίας.

### Πώς εξασφαλίζεται η Æternity;

Η Aeternity χρησιμοποιεί μια πολυδιάστατη προσέγγιση για να διασφαλίσει ότι η blockchain της παραμένει ασφαλής και αποδοτική, εξυπηρετώντας τις ανάγκες συναλλαγών υψηλού εύρους ζώνης και περίπλοκων έξυπνων συμβολαίων. Στον πυρήνα των μέτρων ασφαλείας της βρίσκεται η χρήση ενός τύπου ασφαλούς εικονικής μηχανής (VM), η οποία μειώνει σημαντικά τους κινδύνους ευπαθειών και επιθέσεων που θα μπορούσαν να θέσουν σε κίνδυνο το σύστημα. Αυτή η VM διασφαλίζει ότι μπορούν να εκτελεστούν μόνο καλά ορισμένες και ασφαλείς λειτουργίες, παρέχοντας μια σταθερή βάση για την ανάπτυξη έξυπνων συμβολαίων.

Οι αποκεντρωμένοι μηχανισμοί συναίνεσης της πλατφόρμας ενισχύουν περαιτέρω την ασφάλειά της. Διανέμοντας τον έλεγχο και τη λήψη αποφάσεων σε ένα ευρύ δίκτυο συμμετεχόντων, η Aeternity μειώνει τους κινδύνους που σχετίζονται με τα κεντρικοποιημένα συστήματα, όπου ένα μοναδικό σημείο αποτυχίας θα μπορούσε να οδηγήσει σε σημαντικές παραβιάσεις ασφαλείας. Αυτός ο αποκεντρωμένος σχεδιασμός είναι κρίσιμος για τη διατήρηση της ακεραιότητας και της εμπιστοσύνης της blockchain.

Η υλοποίηση των καναλιών κατάστασης από την Aeternity είναι άλλο ένα κλειδί που ενισχύει την ασφάλ

### Πώς θα χρησιμοποιηθεί το Æternity;

Το Æternity θεωρείται ως μια πλατφόρμα blockchain που σχεδιάστηκε για να αντιμετωπίσει μερικές από τις κρίσιμες προκλήσεις που αντιμετωπίζουν οι τομείς του blockchain και των κρυπτονομισμάτων, ιδιαίτερα όσον αφορά την κλιμακωσιμότητα, την ασφάλεια και την αποδοτικότητα. Η κύρια χρήση του επικεντρώνεται στο να λειτουργεί ως πλατφόρμα ανάπτυξης για εφαρμογές που βασίζονται σε δεδομένα, αξιοποιώντας την τεχνολογία blockchain νέας γενιάς του για να προσφέρει σημαντικά τεχνικά πλεονεκτήματα.

Ένα από τα βασικά χαρακτηριστικά του Æternity είναι η προσέγγισή του στην κλιμακωσιμότητα. Σε αντίθεση με τα παραδοσιακά blockchain που συχνά αντιμετωπίζουν προβλήματα συμφόρησης του δικτύου και υψηλά τέλη συναλλαγών κατά τις περιόδους αιχμής, το Æternity έχει σχεδιαστεί ώστε να μην έχει όρια κλιμάκωσης. Αυτό επιτυγχάνεται μέσω των καναλιών κατάστασης, τα οποία επιτρέπουν τις εκτελέσεις συμβολαίων εκτός αλυσίδας. Αυτά τα κανάλια κατάστασης διασφαλίζουν ότι τα συμβόλαια μπορούν να εκτελεστούν εκτός της κύριας αλυσίδας, μειώνοντας το φορτίο στο δίκτυο και επιτρέποντας ταχύτερους χρόνους συναλλαγών. Μόνο σε περιπτώσεις διαφωνιών αυτές οι συναλλαγές αγγίζουν το blockchain, όπου επιλύονται με αυτοδικαίωση.

### Ποια είναι τα κύρια γεγονότα που έχουν συμβεί για το Æternity;

Η Æternity έχει σηματοδοτήσει την παρουσία της στον κόσμο του blockchain μέσω μιας σειράς σημαντικών ορόσημων και αναπτύξεων από την ίδρυσή της. Ιδρύθηκε το 2017, αυτή η πλατφόρμα blockchain έχει αφιερωθεί στην αντιμετώπιση κρίσιμων αναποτελεσματικοτήτων στην αγορά των κρυπτονομισμάτων, επικεντρώνοντας στην ενίσχυση της κλιμακωσιμότητας των έξυπνων συμβολαίων και των αποκεντρωμένων εφαρμογών (dApps), εισάγοντας καινοτόμες λύσεις όπως το sharding, και διευκολύνοντας την εκτέλεση συμβολαίων εκτός αλυσίδας.

Ένα από τα καθοριστικά στιγμιότυπα για την Æternity ήταν η εκκίνηση του κύριου δικτύου της το 2018, ένα σημαντικό βήμα που σημάδεψε τη μετάβασή της σε μια πλήρως λειτουργική πλατφόρμα blockchain. Αυτή η εκκίνηση έθεσε τις βάσεις για την πλατφόρμα να αρχίσει την υλοποίηση των βασικών της χαρακτηριστικών και τεχνολογιών.

Ακολουθώντας την εκκίνηση του κύριου δικτύου, η Æternity παρουσίασε τα State Channels, μια επαναστατική λειτουργία που επιτρέπει την εκτέλεση έξυπνων συμβολαίων εκτός αλυσίδας. Αυτή η καινοτομία έχει σχεδιαστεί για να μειώσει σημαντικά το φορτίο στο blockchain, εξασφαλίζοντας ταχύτερες συναλλαγές και χαμηλότερο κόστος, διατηρώντας παράλληλα την ασφάλεια και την ακεραιότητα.



Aeternity (AE) is a blockchain platform that focuses on high bandwidth transacting, purely-functional smart contracts, and decentralized oracles. It was founded in 2017, and seeks to eliminate inefficiencies in the crypto market by increasing scalability of smart contracts and dApps, sharding, and off-chain contract execution. The Turing-complete smart contracts on the Aeternity chain allow for transaction execution without third parties or intermediaries. Aeternity also has state channels to enable off-chain smart contract settlements which only touch the blockchain should a disagreement in the contract arise, acting as a self-arbitrating crypto court. The Aeternity blockchain is also built upon state-of-the-art cryptographic data structures which give rise to robust efficiency, strong security, and the elimination “single point of failure” (SPOF) issues.

BitShares Blockchain is a decentralized “Blockchain as Organization” (BaO); an industrial-grade decentralized open source platform built to run high-performance financial technology operations. It represents the first decentralized autonomous decentralized community that enables its core utility token (BTS) holders to decide the Blockchain future direction in order to develop and maintain a wide range of decentralized financial technology products, features and functions. BitShares Blockchain is a Blockchain that permanently records financial technology operations between different Blockchain accounts and facilitates a wide range of access controls across BitShares Blockchain user financial means.

BitShares Blockchain is a technology that supports the digital generation entrepreneurs, investors, and developers with a common interest in building and participating in free market solutions by leveraging the power of globally decentralized consensus and decision making. Consensus technology has the power to do for economics what the internet did for information. It can harness the combined power of all humanity to coordinate the discovery and aggregation of real-time knowledge, previously unobtainable. This knowledge can be used to more effectively coordinate the allocation of resources toward their most productive and valuable use.

BitShares looks to extend the innovation of the Blockchain to all industries that rely upon the internet to provide their services. Whether its banking, stock exchanges, lotteries, voting, music, auctions or many others, a digital public ledger allows for the creation of distributed autonomous companies (or BaO) that provide better quality services at a fraction of the cost incurred by their more traditional, centralized counterparts. The advent of (BaO) ushers in a new paradigm in organizational structure in which companies can run without any human management and under the control of an incorruptible set of business rules. These rules are encoded in publicly auditable open source software distributed across the computers of the companies’ shareholders, who effortlessly secure the company from arbitrary control. BitShares does for business what bitcoin did for money by utilizing distributed consensus technology to create companies that are inherently global, transparent, trustworthy, efficient and most importantly profitable.

BitShares has went through many changes and has done its best to stay on top of Blockchain technology. BitShares is using Consensus as the mechanism by which organized people decide upon unitary rational action. While not considered technology in the traditional since, consensus “technology” is the basis of democratic governance and the coordination of free market activity first coined by Adam Smith as the “Invisible Hand.” The process of consensus decision-making allows for all participants to consent upon a resolution of action even if not the favored course of action for each individual participant. Bitcoin was the first system to integrate a fully decentralized consensus method with the modern technology of the internet and peer-to-peer networks in order to more efficiently facilitate the transfer of value through electronic communication. The proof-of-work structure that secures and maintains the Bitcoin network is one manner of organizing individuals who do not necessarily trust one another to act in the best interest of all participants of the network. The BitShares ecosystem employs Delegated Proof of Stake in order to find efficient solutions to distributed consensus decision making.

Wanchain is a distributed ledger that allows for cross-chain transactions and the interoperability of multiple chains. Although Wanchain facilitates transactions between blockchains, it is also a stand-alone blockchain that runs autonomously. The protocol acts as a distributed ledger that processes and maintains records of cross-chain transactions.

Transactions on Wanchain do not only occur between different public blockchains but between private chains as well. As an Ethereum (ETH) fork, Wanchain enjoys some of the properties of the Ethereum blockchain. The protocol securely and autonomously processes applications via smart contracts.  The use cases for Wanchain include decentralized exchanges (DEXs), lending and borrowing platforms, stablecoins, crowdfunding, multi-currency payments and settlements.

The platform is totally decentralized and requires no custodian party to manage or confirm transactions. Unlike other cross-chain systems, Wanchain does not rely on a third-party platform to authenticate transactions. The locked account mechanism is used to secure and manage accounts on the network, eliminating third-party interferences.
